在 UIResponder中存在这么一套方法
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent
*)event
__OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent
*)event
__OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent
*)event
__OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);
这就是执行摇一摇的方法。那么怎么用这些方法呢？
很简单，你只需要让这个Controller本身支持摇动
同时让他成为第一相应者：
- (void)viewDidLoad
{
[superviewDidLoad];
// Do any additional setup after loading the view, typically from a
nib.
[[UIApplicationsharedApplication]
setApplicationSupportsShakeToEdit:YES];
becomeFirstResponder];
*)event
{
//检测到摇动
}
- (void) motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent
*)event
{
//摇动取消
}
- (void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent
*)event
{
//摇动结束
if
(event.subtype == UIEventSubtypeMotionShake) {
//something
happens
}
